Title: Getter for nuclear fuel elements
IPC: G21C3/17
Filed: 1974-04-01
Abstract: A nuclear fuel element for use in the core of a nuclear reactor is disclosed and has disposed therein an improved getter capable of gettering reactive gases including a source of hydrogen.

Patent ES-431237-A1 (ES)
Title: Membrane pump
IPC: F04B43/06
Filed: 1974-10-22
Abstract: An air pressure-operated membrane pump for pumping a liquid comprises a housing including a chamber which is divided into liquid and air compartments by a floppy flexible membrane extending across it. The air compartment has an air inlet and outlet connected by a duct to the throat of a venturi to which an air supply under pressure is connected. The outlet from the venturi is controlled by a control valve which is itself opened and closed by the movement of the diaphragm to which a closure member of the valve is connected by a control member. When the valve is open, air flows through the venturi and causes air to be drawn from the air compartment of the pump to move the diaphragm in a direction to draw liquid into the liquid compartment in an intake stroke. At the end of this stroke, the part of the membrane to which the control member is fixed moves and closes the control valve. This causes air under pressure to flow from the throat of the venturi into the air compartment to move the diaphragm in a direction to expel liquid from the liquid compartment in a pumping stroke and again at the end of this stroke movement of the diaphragm moves the control member to shut the valve so that the cycle of operations is repeated, the control of operation of the pump thus being effected entirely by the movement of the membrane itself without any external agency.
Patent ES-447657-A1 (ES)
Title: Method of terminating optical fibers
IPC: G02B6/38
Filed: 1976-05-06
Abstract: A method of holding the bared end of a plastic sheathed optical fiber accurately on axis of a metal ferrule through which it is threaded while a potting compound is cured which cements the assembly. The method uses a silicone rubber jig cast from an accurately machined mold. The resilience of the jig enables variations in diameter to be accommodated so that holes for locating the ferrule and the bared fiber end need to be coaxial, but their size is not critical. Many jigs can be cast from a single mold reducing costs and increasing output as compared with prior methods.

Title: Process for dyeing textile materials incorporating polyester fibres
IPC: D06P3/54
Filed: 1978-01-18
Abstract: In the dyeing of textile material consisting wholly or partly of polyester fibres with disperse dyes, oligomer deposits on the textile material and on elements of the apparatus used are to be prevented. The process is suitable for dyeing with acid and alkaline liquors. The textile material is first subjected to an oligomer deposit avoidance pre-clearing (pre-cleaning) treatment in a dye-free alkaline liquor. This treatment is effected either at a temperature of between 100 and 180 DEG C with the liquor containing 0.01-3 g/l of a carrier or at a temperature between 10 and 100 DEG C with the liquor containing 5-20 g/l of a carrier. This is followed, in a second step, by dyeing with the disperse dye liquor either obtained by adding dye to the used pre-clearing liquor or freshly prepared.
Patent ES-468628-A1 (ES)
Title: Crud handling circuit
IPC: C22B60/02
Filed: 1978-04-07
Abstract: A method for handling the problem of crud formation in the solvent extraction of wet-process phosphoric acid is described. Crud is the name ordinarily given to the thick interfacial layer of semi-floatable material which tends to form and accumulate, and which interferes with many of the extraction processes and, in particular, with the solvent extraction of wet-process phosphoric acid. The method described provides for the operation of the solvent extraction stages in a manner that allows the formation and temporary accumulation of crud in those stages whereupon the solvent and the crud are then removed from the extraction stages and treated in a series of operations which include a clarification step, an acid removal step, a water wash step and a caustic treatment step, which steps effectively separate the solvent from the crud, and remove the crud components from the system and regenerate otherwise unusable solvent. The invention is particularly applicable to the solvent extraction of wet-process phosphoric acid for the recovery of uranium by the reductive stripping technique.
